Republican Sen. Pat Roberts easily wins re-election, defeating Democratic challenger Jim Slattery.
The Associated Press declared Roberts the winner based on an analysis of information from voters interviewed as they left the polling places. The interviews were conducted for The Associated Press by Edison Media Research and Mitofsky International.
Roberts was seen as the favorite in the race because a Democrat
hasn't won a Senate race in GOP-leaning Kansas since 1932.
The incumbent portrayed himself as someone who has delivered federal funds and favorable legislation for Kansas. He also raised 3 1/2 times as much campaign money as Slattery -- more than $5.2 million by mid-October.
